I agree that it's a shame the promos are no longer near the quality they used to be - or used anywhere near as much. But I do think they still show them a tiny bit - I could swear I've seen them air during the Biggest Loser several times over the past year or so. The tie in is pretty obvious, but I do think they air on the network at that time.

That is really the only time I have seen them. Yes, you see them sparingly but there was once a time where you saw them constantly in daytime (during the Today show, talks shows, etc) and in late night and scattered about every now and then in primetime. Now, you barely see them unless it's TBL or sometimes during sweeps they will show them a little (emphasis on LITTLE) more.
